- 2. Commit Related Changes A commit should be a wrapper for related changes. For example, fixing two diffe- rent bugs should produce two separate commits. Small commits make it easier for other developers to understand the changes and roll them back if something went wrong. With tools like the staging area and the ability to stage only parts of a file, Git makes it easy to create very granular commits. Commit Often Committing often keeps your commits small and, again, helps you commit only related changes. Moreover, it allows you to share your code more frequently with others. That way it‘s easier for everyone to integrate changes regularly and avoid having merge conflicts. Having few large commits and sharing them rarely, in con- trast, makes it hard to solve conflicts. Don‘t Commit Half-Done Work You should only commit code when it‘s completed. This doesn‘t mean you have to complete a whole, large feature before committing. Quite the contrary: split the feature‘s implementation into logical chunks and remember to commit early and often. But don‘t commit just to have something in the repository before leaving the office at the end of the day. If you‘re tempted to commit just because you need a clean working copy (to check out a branch, pull in changes, etc.) consi- der using Git‘s «Stash» feature instead. Test Code Before You Commit Resist the temptation to commit some- thing that you «think» is completed. Test it thoroughly to make sure it really is completed and has no side effects (as far as one can tell). While committing half- baked things in your local repository only requires you to forgive yourself, having your code tested is even more important when it comes to pushing/sharing your code with others. Write Good Commit Messages Begin your message with a short sum- mary of your changes (up to 50 charac- ters as a guideline). Separate it from the following body by including a blank line. The body of your message should provide detailed answers to the following questions: – What was the motivation for the change? – How does it differ from the previous implementation? Use the imperative, present tense («change», not «changed» or «changes») to be consistent with generated messa- ges from commands like git merge. Version Control is not a Backup System Having your files backed up on a remote server is a nice side effect of having a version control system. But you should not use your VCS like it was a backup system. When doing version control, you should pay attention to committing se- mantically (see «related changes») - you shouldn‘t just cram in files. Use Branches Branching is one of Git‘s most powerful features - and this is not by accident: quick and easy branching was a central requirement from day one. Branches are the perfect tool to help you avoid mixing up different lines of development. You should use branches extensively in your development workflows: for new fea- tures, bug fixes, ideas… Agree on a Workflow Git lets you pick from a lot of different workflows: long-running branches, topic branches, merge or rebase, git-flow… Which one you choose depends on a couple of factors: your project, your overall development and deployment workflows and (maybe most important- ly) on your and your teammates‘ personal preferences. However you choose to work, just make sure to agree on a com- mon workflow that everyone follows.
